MODE OF BACKING UP PICTURES ON GLASS.

Specification forming part of Letters Patent No. 26,733, dated January3, 1860.

To all whom it may concern:

Be it known that we, THOMAS FRY, of the city of Brooklyn, county ofKings, and State of New York, and CHARLES A. SEELY, of the city, county,and State of New York, have made a new and useful Improvement in thePictures called Ohemitypes, and applicable also to other pictures ordesigns on glass; and we do declare that the following is a full andexact description thereof.

The nature of our invention consists in the application of wax or othertranslucent substances to the back of the chemitype or other pictures onglass and coloring the same, thereby producing a clearness and softnessof effect which have not before been obtained.

To enable those skilled in the art to make and use our invention, wewill proceed to the description of our process.

We take a chemitype produced by any of the known methods, before anycoloring or backing has been used, and apply to the impression side alayer of wax or its equivalent, either by flowing melted wax or byattaching sheets of wax. When the wax is spread to a suitable thicknesswe then reduce the surface or make it even by means'of scraping with aknife or other suitable implement. The wax may be of a uniform thicknessof a sixteenth of an inch, more or less, or may be of an uneventhickness, to suit the nature of the picture. We now lay on colors inoil, water, or powder, or by meansof tinted paper.

The same procedure is employed in finishing other designs on glass.

What we claim, and desire to secure by Letters Patent, is-

The process of using wax, stearine, spermaceti, or other substances orcompositions substantially the same for the purpose of backing up and asa medium of color for the chemitype and other pictures or designs onglass.
